LA5617
Multi-System Power Supply for Audio Equipment
Overview
The LA5617 is a multi-system power supply IC with a
built-in on/off control function. It is optimal for use as the
power supply IC in CD players, mini-component stereo
systems, and other microcontroller controlled audio
equipment.
Functions
• Power supply IC with ±7.5 V outputs (±1.5 A) and an
on/off control function.
• The LA5617 is pin compatible with the LA5618.
